On Demand Hot Water Heaters

[TheWoodYard]

Hey guys, does anyone know a good supplier for on demand hot water heaters? Looking for a system that would be capable of water temps of 170F+.
Cheers!

Rinnai, from your local plumbing supplier.

Also recommend the Nortiz commercial line, again from a local supplier.

Yes, either of those brands, obtained from a plumbing professional, should be a good fit.

I personally would recommend going with Natural Gas/Propane as opposed to the electric versions.

Good luck!

Tankless Hot Water

Takagi makes higher BTU Tankless HW Heaters. Make sure you talk with a plumber, vent lines, gas lines are things you need to look at, most of the higher btu units take 1 1/2" gas lines and up! Another condisderation is incoming water temp and flow. I was just going to do one until I talked to my plumber and found out all the stuff I had to chage in order to make it work.

Rheem also make large btu tankless

We use a Nortz and it puts out 180 degree water.

A tube and shell heat exchanger can do it for you, too...if you have excess steam.

Not to hijack the thread, but we were going to put on-demand gas water heaters in our distillery project, but we ended up going with a solar tube array, which is supplemented by steam when our supply is below temp. I was surprised how fast the steam was!

I have the solar set to 180. Getting all the settings right was a bit of a bummer, but it works well now! Tax credits and rebates for our area ended up exceeding the cost of the system :-D I only have to use the steam if I drained the res after sundown and I'm trying to use the HL early in the morning.

Might not be a great solution for every situation, but works a treat for our application!

What is your fuel source? Do you have steam? If so check these guys out...

I haven't used them yet, just found out about them, but looks promising. Shell and tube, specializing in sanitary applications.

I like the post re: solar thermal. It is excellent if your system is set up for storage and centralized distibution.
